The comet PanSTARRS in that day has moved northward at about 4.5 degrees northwest of the Andromeda Galaxy (M31). It was good transparency condition, I could detect clearly a 3rd magnitude coma and a widely spread fan-shaped dust tail with an angle of about 120 degrees or so in northeast direction. The comet will continue to move northward and be a circumpolar comet in end of Apr 2013.
